CD55, also known as DAF (decay accelerating factor), is expressed on the surfaces of red blood cells, hematopoietic cells and many non-hemotopietic cells. There are two isoforms of mouse CD55, a GPI-anchored isofrom and a transmembrane isoform. Both are recognized by RIKO-3. The function of CD55 is to protect damage by complement deposition.

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 0.06 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Antigen Details

60-70 kd single chain glycoprotein. While human CD55 contains only one CD55 gene, two distinct CD55 genes have been identified in the mouse, referred to as GPI-DAF and transmembrane(TM)-DAF. GPI-DAF is expressed only in testis.

Red blood cells and most of the splenocytes, including B cells and T cells, and also many non-hematopoetic cells.

Protect from complement attack by inhibition the deposition of C3 on antibody-sensitized cells.
